(54) Wet pick-up type vacuum cleaner


(57) A motor-fan unit for a wet pick-up type of vacuum cleaner comprising a fan-section (50) and a separately ventilated motor section (10). A motor-end bracket in the motor housing structure serves as a common end wall with the fan section and carries a bearing (40) for the common shaft (15) of the motor and fan. A baffle (38) carried by the motor-end bracket within the fan section has an apertured central portion (52), at least partly enclosing the bearing, to provide a passageway for high velocity air sealing the bearing from detergent-containing cleaning liquid entrained in working air drawn into the fan section and whereby said baffle portion (38) of said passageway (51) extends said passageway radially inwardly of the periphery of said support means and therebey locates said annular orifice (52) within said space between said bearing and the most closely adjacent fan (66) of said fan system.
